SU721650A1 - Cooling column for loose materials - Google Patents

Description

The invention relates to a technique for drying strong materials, such as grains, and can be used in agriculture and in the chemical industry. Cooling columns for bulk materials are known, containing concentrically arranged perforated Ø1 cylinders, in the annular space between which they are located above the upper section of the material with the material blown by cold air. In order to ensure constant filling of the column. Electric grain level sensors have been installed, which are periodically1, as the column is filled, an exhaust device is put into operation, consisting of a sliding gate rotating from the motor-reduct 1. In a known cooling column, the grain release system, consisting of a sluice gate with a motor reputa- tor controlled by grain level sensors, is very folded, material-intensive and unreliable, which causes frequent failures and grain drying processes. Cooling rods for bulk materials are also known, containing two concentrically arranged cylinders with a conical base at the outer first cylinder, forming an annular chamber for moving the cooling material from top to bottom, a central collector for exhaust air exhaust and an exhaust valve installed at the outlet of the chamber, filled with a cone, connected through a cone, Ti with control mechanism C 2. These columns by the number of common signs closest to write off. The disadvantage of such speakers is the difficulty of using a discharge valve and power consumption of 1.1%.

The purpose of the invention is to reduce energy consumption by providing self-regulation to the load.

The goal is achieved by the fact that in the proposed column in the upper part of the chamber there is a compartment adjacent to the collector, and the control mechanism is designed as a flashing light in the compartment with a flashing light through the stake. a lecturer and a coupler with a pull, with a counter-weight mounted on the free end of the rocker arm, equipped with a protective casing at the top.

The drawing shows schematically a longitudinal section of the described cooling pit.

The cooling column contains concentrically arranged cylinders 1, 2, with a conical base at the pilindre 1, forming an annular chamber 3, a loading device 4, a suction port 5 with a fan 6, a compartment 7 for material passage, a control mechanism in the form of a flap 8 like a flasher connected to the link 9, the beam 10, the weight of the weight 11, the weight 12 and the outlet behind the body in the form of a cone 13; The casing 14 serves to prevent the counterbalance from falling back. The valve 8 is located in compartment 7.

The column works as follows.

The material entering through the loading device 4 fills the chamber 3 to the upper edge of the compartment 7, and then converges into the compartment and fills the space above the flap 8. Under the weight of the material, the flap 8 tilts down and rotates the beam 1O, which 12 squeezes the cone 13, locking the outlet opening of the column. The diameter of the outlet and the stroke of the cone 13 are selected so that the material outflow from the column obviously exceeds the productivity of its flow. The flap 8 remains in the lowered position until the material level in the working space of chamber 3 is lowered to the lower edge of the compartment 7 and the material above the flap 8 is again

poured into the working space of chamber 3. Clearing the material from the material, the damper 8 by the counterweight 11 through the yoke 1O and the link 9 rises and returns to its original substitution, dragging the opening hole of the column behind the connecting rod 12 and the cone 13. Then the cycle is repeated. So the material level

in the working space of the chamber, the column oscillates from the lower to the upper edges of the compartment 7, ensuring a constant filling of the perforated part of the cooling column and, consequently, its reliable operation and high-quality cooling of the material after heating in the dryer.
